Description

本発明は、トランス脂肪酸含量が低いにもかかわらず、水素添加臭(水添臭又は硬化臭と呼ばれることもある)の風味を有する油脂組成物に関するものである。
また、本発明は、トランス脂肪酸含量が低いにもかかわらず、水素添加臭の風味を有する食品に関するものである。
The present invention relates to an oil and fat composition having a flavor of hydrogenated odor (sometimes referred to as hydrogenated odor or cured odor) despite the low trans fatty acid content.
The present invention also relates to a food having a hydrogenated odor flavor despite the low trans fatty acid content.

動植物油脂を部分水素添加して得られる硬化油(以下、部分水素添加して得られる硬化油は、部分水素添加油脂とする)は、サラダ油等に代表される液状油と比べ、耐熱性、酸化安定性に優れるため、フライドチキン、フライドポテト、バターピーナッツ、ドーナツ等に用いられる加熱調理用油脂として従来から用いられて来た。また、部分水素添加油脂は、可塑性を有することから、マーガリン、ショートニング等の可塑性油脂組成物やホイップクリーム等の起泡性水中油型乳化物等の広く油脂加工食品にも用いられて来た。   Hardened oil obtained by partial hydrogenation of animal and vegetable fats and oils (hereinafter, the hardened oil obtained by partial hydrogenation is referred to as partially hydrogenated fats and oils) is heat resistant and oxidized compared to liquid oils such as salad oil. Since it is excellent in stability, it has been conventionally used as a cooking oil for use in fried chicken, french fries, butter peanuts, donuts and the like. In addition, since partially hydrogenated fats and oils have plasticity, they have been widely used in processed fat and oil processed foods such as plastic oil and fat compositions such as margarine and shortening, and foamable oil-in-water emulsions such as whipped cream.

動植物油脂の部分水素添加油脂は、水素添加によって生成するトランス脂肪酸を含有している。近年、トランス脂肪酸に関しては、ヒトをはじめ動物が長期間多量に摂取した場合には、血中総コレステロール値及び悪玉と呼ばれる低密度リポ蛋白質コレステロール値を高め、肥満や虚血性心疾患などの原因となりうるという学説が欧州や米国から出て来ており、一定水準以上のトランス脂肪酸を含有する食品については表示を義務化する等の対策をとる国が増えてきている。我が国においても世界的な流れを受け、食品中のトランス脂肪酸含量を低減させる試みが検討されており、加熱調理用油脂や油脂加工食品についても、トランス脂肪酸含量の低減化が求められている。   The partially hydrogenated fat of animal and vegetable fats and oils contains trans fatty acids generated by hydrogenation. In recent years, trans-fatty acids have increased blood total cholesterol levels and low-density lipoprotein cholesterol levels called bad, which can cause obesity and ischemic heart disease when animals, including humans, are ingested in large quantities for a long time. The theory of “Uru” has emerged from Europe and the United States, and an increasing number of countries are taking measures such as requiring labeling for foods containing trans fatty acids above a certain level. In Japan, attempts have been made to reduce the trans fatty acid content in foods in response to the global trend, and it is also required to reduce the trans fatty acid content in cooking fats and oils and processed foods.

動植物油脂の部分水素添加油脂中におけるトランス脂肪酸含量の低減化に関しては、水素添加反応の工程で、触媒や温度等の反応条件を工夫する試みがなされている(例えば、特許文献1、2)。   Regarding the reduction of the trans fatty acid content in the partially hydrogenated fats of animal and vegetable fats and oils, attempts have been made to devise reaction conditions such as catalyst and temperature in the hydrogenation reaction step (for example, Patent Documents 1 and 2).

一方、動植物油脂の部分水素添加油脂は、水素添加臭と呼ばれる独特の風味を有しており、例えば、フライドチキンやドーナツ等では、水素添加臭の独特の風味が消費者に慣れ親しまれている。従って、水素添加臭は、商品の個性を特徴付ける重要な風味の一部として定着しているものも多い。
この動植物油脂の部分水素添加油脂の水素添加臭は、前述したトランス脂肪酸に起因することが知られている。
従って、前述のトランス脂肪酸含量を低減させる試みにより、トランス脂肪酸含量を減らすと、水素添加臭の独特な風味が失われるという問題があった。
On the other hand, partially hydrogenated fats of animal and vegetable fats and oils have a unique flavor called hydrogenated odor. For example, in fried chicken and donuts, the unique flavor of hydrogenated odor is familiar to consumers. . Therefore, many hydrogenated odors have been established as part of an important flavor that characterizes the individuality of products.
It is known that the hydrogenated odor of partially hydrogenated fats and oils of animal and vegetable fats and oils is attributed to the above-mentioned trans fatty acids.
Therefore, when the trans fatty acid content is reduced by the above-described attempt to reduce the trans fatty acid content, there is a problem that the unique flavor of the hydrogenated odor is lost.

以上のような背景から、動植物油脂の部分水素添加油脂の独特な風味である水素添加臭の風味を有したまま、トランス脂肪酸含量をできる限り低減した油脂の開発が望まれていた。
特開平7−316585号公報 特開2006−320275号公報
From the background as described above, it has been desired to develop fats and oils with a trans fatty acid content reduced as much as possible while maintaining the flavor of hydrogenated odor, which is a unique flavor of partially hydrogenated fats of animal and vegetable fats and oils.

以下、本発明について詳細に説明する。
まず、本発明の油脂組成物について説明する。
本発明の油脂組成物は、部分水素添加油脂を1〜30質量%含有し、該部分水素添加油脂の過酸化物価が0.04〜7であることを特徴とする。
Hereinafter, the present invention will be described in detail.
First, the oil and fat composition of the present invention will be described.
The oil and fat composition of the present invention contains 1 to 30% by mass of partially hydrogenated oil and fat, and the peroxide value of the partially hydrogenated oil and fat is 0.04 to 7.

部分水素添加油脂とは、動植物油脂を部分水素添加して得られる油脂である。部分水素添加油脂は、部分水素添加硬化油、部分水添油と呼ばれることもある。極度硬化油が原料油脂を構成する全ての不飽和脂肪酸の二重結合に水素を付加することで構成脂肪酸の全てを飽和脂肪酸としたものであるのに対して、部分水素添加油脂は原料油脂を構成する一部の不飽和脂肪酸の二重結合に水素を付加したものであり、部分水素添加油脂は構成脂肪酸に不飽和脂肪酸が残存しているものである。水素付加の反応時に副反応として、不飽和脂肪酸の二重結合がシス型からトランス型への異性化を起こすため、不飽和脂肪酸が残存している部分水素添加油脂には、通常、トランス脂肪酸が含まれるものである。   Partially hydrogenated fats and oils are fats and oils obtained by partially hydrogenating animal and vegetable fats and oils. Partially hydrogenated oils and fats are sometimes referred to as partially hydrogenated hydrogenated oils and partially hydrogenated oils. While extremely hardened oils are made by adding hydrogen to the double bonds of all unsaturated fatty acids that make up the raw fats and oils, all of the constituent fatty acids are made into saturated fatty acids, whereas partially hydrogenated fats and oils are made from raw fats and oils Hydrogen is added to a double bond of a part of the unsaturated fatty acid constituting the partially hydrogenated fat and oil, and the unsaturated fatty acid remains in the constituent fatty acid. As a side reaction during the hydrogenation reaction, the unsaturated fatty acid double bond causes isomerization from the cis form to the trans form. It is included.

部分水素添加油脂の原料となる動植物油脂としては、通常、食用油脂として使用されるものであれば特に制限なく使用することができるが、例えば、大豆油、菜種油、綿実油、コーン油、パーム油、紅花油、ヒマワリ油、牛脂、豚脂等やこれらのエステル交換油、分別油等が挙げられる。   As animal and vegetable fats and oils that are used as raw materials for partially hydrogenated fats and oils, they can be used without particular limitation as long as they are usually used as edible fats and oils. For example, soybean oil, rapeseed oil, cottonseed oil, corn oil, palm oil, Examples include safflower oil, sunflower oil, beef tallow, pork tallow, transesterified oil, fractionated oil, and the like.

部分水素添加油脂は、常法の水素添加方法により製造することができる。例えば、原料油脂である動植物油脂に、ニッケル等の触媒を対油0.01〜0.3質量%添加し、温度120℃〜200℃、水素圧0.01〜0.3MPaの条件で水素添加反応を行うことにより製造することができる。   Partially hydrogenated fats and oils can be produced by a conventional hydrogenation method. For example, 0.01 to 0.3% by mass of a catalyst such as nickel is added to animal and vegetable fats and oils that are raw oils and fats, and hydrogenation is performed under conditions of a temperature of 120 ° C. to 200 ° C. and a hydrogen pressure of 0.01 to 0.3 MPa. It can manufacture by performing reaction.

過酸化物価が上記範囲の部分水素添加油脂としては、過酸化物価が上記範囲であれば特に制限なく使用することができるが、部分水素添加油脂が長期間保存により酸化したものや強制的に空気を吹き込む等による強制的に酸化させたもの等を使用することができる。
なお、油脂の過酸化物価は、「社団法人 日本油化学会 基準油脂分析試験法2.5.2.1−1996」の方法に準じて測定することができる。
このように軽微に酸化して過酸化物価が上記範囲となった部分水素添加油脂を使用すると、トランス脂肪酸含量が少なくても水素添加臭の風味の発現を強めることができるため、トランス脂肪酸含量を低減することができる。

なお、油脂のトランス脂肪酸含量は、AOCS法(Ce1f−96)に準じてガスクロマトグラフィー法にて測定することができる。また、油脂のヨウ素価は、「社団法人 日本油化学会 基準油脂分析試験法2.3.4.1−1996」の方法に準じて測定することができる。

Chicken thigh meat coated with an appropriate amount of 5 parts by weight of garam masala added to 100 parts by weight of commercially available fried flour (Nisshin Flour Milling Co., Ltd.), the fat composition of Example 9 or the fat composition of the flavor standard product Using the product, it was fried at 180 ° C. for 4 minutes to obtain fried chicken.
As a result of evaluating the flavor of fried chicken by a panel of five people, the fried chicken using the oil composition of Example 9 has a sufficient hydrogenated odor equivalent to the fried chicken using the oil composition of the flavor standard product. It had a flavor. Although the oil and fat composition of Example 9 used for frying had less trans fatty acid content than the oil and fat composition of the standard flavor, the resulting fried chicken had a comparable hydrogenated odor flavor. It was.
